Later works were focused on deeper studies of individual FGs and found controversial results: [1]}, [2]} found no central drop in NGC 6482 and RX J1416.4+2315. On the other hand, [3]} found a CC in ESO 3060170, as well as [4]} for RXC J0216.7-4749 and RXC J2315.7-0222 and [5]} for RXJ1159+5531.
It is interesting to note that [6]} studied three of the cited clusters (NGC 6482, RX J1416.4+2315, and ESO 3060170) using radio observations, finding signs of recent AGN activity only in the first two. However, the AGN power computed was not sufficient to remove CCs from these clusters.
